The difference between an early and late diagnosis for glaucoma

SPONSORED

Glaucoma is the world’s leading cause of irreversible blindness. As part of its support for World Glaucoma Week (12-18 March), Specsavers Ópticas is urging people to get their eyes tested regularly to ensure early diagnosis of this common eye condition.

In 2022 Specsavers Ópticas stores in Javea, La Zenia and Fuengirola all shared stories of signs of glaucoma being discovered during routine eye tests, which show the importance of early diagnosis.

Early diagnosis = damage minimised

At Specsavers Ópticas Fuengirola, Ian Elsby went to check whether he could wear contact lenses, just six months after his last eye test. He had no symptoms, his vision was normal and there was no sign of damage to the optic nerve, yet he had high pressure in his eye.

Optometrist and store director, Judith Borland explains: ‘High pressure in the eye is one of the symptoms of glaucoma, so we gave Ian a letter to take to his doctor and request a referral to an ophthalmologist at his local hospital. He was diagnosed with glaucoma and given drops to use at night to control his eye pressure. Fortunately, he was diagnosed at an early stage and still maintains very good vision.’

Later diagnosis = Some peripheral vision loss

In Specsavers Ópticas Javea, Willem Koopmans had been experiencing headaches and noticed that his eyesight was getting worse, but put it down to just needing new glasses. However, during a comprehensive eye test, the team noticed signs of glaucoma, including a deep excavation of the optic nerve in his left eye, which had damaged his peripheral vision. They gave him an urgent referral to San Carlos private hospital, who diagnosed the glaucoma and started Mr Koopmans on treatment.

Optometrist and store director, Cecilia Navarro explains: ‘Thankfully now that he is on treatment the optic nerve excavation will not get any worse and overall, his vision remains good. However, he would have lost a lot more vision if he hadn’t had his eyes tested and urgently sought medical attention.’

Leaving glaucoma too long = Significant permanent vision loss

Unfortunately, if left too late, severe and permanent damage can be caused, as was shown in the case of Douglas Addison. Mr Addison had a family history of glaucoma and was first diagnosed with it 10 years ago, but thought it was under control. In 2021 he noticed he was losing his peripheral vision, a common sign that the glaucoma is permanently damaging sight, and booked an eye test at Specsavers Ópticas in La Zenia. During the test the optometrist found that his eye pressure was extremely high, they urgently referred Mr Addison to hospital where they confirmed his diagnosis and performed a surgical procedure to stop the glaucoma getting worse. Unfortunately, he lost 75% of the vision in his right eye. But Mr Addison remains very grateful to the team at the La Zenia store for the referral, and the surgical team who stopped him losing vision in both eyes.

The experts at Specsavers Ópticas hope that by sharing these three cases, people will be encouraged to get their eyes tested in March, as part of World Glaucoma Week. Visit www.specsavers.es to find your nearest store and book an eye test.
